STANDARD OF CONDUCT FOR DEBTORS IN OBLIGATIONS
Civil law establishes that a debtor must act with the prudence and care of a “good family father”—a concept that implies responsible, attentive, and foreseeable behavior.
This standard applies to all types of obligations: economic, contractual, family-related, or arising from commercial relationships. Its purpose is to ensure that the debtor does not fulfill obligations in a careless, improvised, or negligent manner.
In everyday situations—such as loan repayments, product deliveries, or entrusted tasks—the assessment hinges on whether the debtor acted as a reasonable person would under similar circumstances.
PROFESSIONAL LIABILITY FOR LACK OF DILIGENCE
When the obligation involves a specialized activity—such as medical, technical, legal, or construction services—the required level of diligence is higher. In these cases, the debtor’s conduct is evaluated based on the nature of the profession and its standard practices.
This means that electricians, lawyers, or architects must perform their duties using the knowledge, skills, and care inherent to their profession. If a professional falls below the expected standard, they may be held civilly liable.
A common example is when a mechanic returns a vehicle with unresolved issues due to inadequate inspection. In such situations, diligence is assessed by comparing the professional’s actions with those of a competent peer in the same field.
LEGAL CONSEQUENCES OF LACK OF DILIGENCE
Failure to exercise proper diligence may result in:
- Liability for damages and losses
- Termination of the contract if the breach is serious
- Obligation to redo the service at no additional cost
Additionally, when the service is professional in nature, the lack of diligence may be evaluated in conjunction with applicable special laws, technical regulations, or ethical standards of the sector.
In summary, the debtor’s diligence is a key factor in determining whether an obligation has been properly fulfilled. The general standard requires behavior aligned with that of a prudent and careful person. In professional contexts, the standard is elevated according to the field’s technical expectations. These rules allow for an objective assessment of negligence and its legal implications.
